Nivada Grenchen F77 Chrono MecaquartzvsYema Navygraf Chrono

The Nivada Grenchen F77 Chrono Mecaquartz is praised for its solid case build, legible dial with applied indices and lume, and a domed sapphire crystal. Owners appreciate the mecaquartz movement for its slimmer profile, affordability, and reliability, with some finding the finishing excellent and the watch well-constructed for its price range of $550-$750. However, one owner reported abysmal crown action and a gritty winding feel, while another disliked the meca-quartz movement itself. The integrated bracelet's connection to the case is criticized for effectively increasing the lug-to-lug distance, potentially impacting wearability on smaller wrists. On balance, owners rate the Nivada Grenchen F77 Chrono Mecaquartz highly for its value and build quality, despite some reservations about the movement and bracelet integration.

Owners praise the Yema Navygraf Chrono for its handsome, versatile design and the value offered by its Valjoux 7750 movement. A reviewer notes the 40mm case's fully polished finish, which some feel clashes with its sporty aesthetic, and mentions its 13.9mm thickness is noticeable. One owner reported wearing the Yema Navygraf Chrono for two months without issues, receiving compliments. On balance, owners and reviewers find the Yema Navygraf Chrono to be a good-looking and well-specced watch for its price.
